CROSS-REFERENCE TO RELATED APPLICATION

The present application is a continuation of International Application No. PCT/CN2018/113844, filed Nov. 2, 2018, the entire disclosure of which is incorporated herein by reference.

BACKGROUND Technical Field

This application relates to the field of mobile communications technologies, and in particular, to a method for determining uplink control information and a communications device.

Related Art

In a 5G new radio (NR) system, ACK/NACK multiplex transmission is supported. That is, ACK/NACK corresponding to a plurality of physical uplink control channels (PDSCHs) is transmitted by a physical uplink control channel (PUCCH). When it is configured that the quantity of ACK/NACK bits is determined semi-statically, the terminal determines the quantity of ACK/NACK bits according to a configured relevant parameter.

An ultra-reliable low-latency communication (URLLC) service has a high requirement on delay. If the URLLC service and an enhanced mobile bandwidth (eMBB) service share a same downlink control information (DCI) format, a value range of each information domain in DCI needs to satisfy requirements of the URLLC service and the eMBB service at the same time. However, this results in a large amount of redundant information in feedback information.

The technical solutions in the implementations of the present invention are mainly applied to a 5G mobile communications system. Certainly, the technical solutions in the implementations of the present invention are not limited to the 5G mobile communications system, and may be further applied to other kinds of mobile communications systems.

An implementation of this application provides a method for determining uplink control information. FIG. 2 is a schematic flowchart of a method for determining uplink control information according to an implementation of this application. As shown in FIG. 2, the method includes the following steps:

Step 201: A communications device obtains a target parameter set, where the target parameter set includes at least one first parameter value and at least one second parameter value, the at least one first parameter value is used for transmitting a first kind of data, and the at least one second parameter value is not used for transmitting the first kind of data.

Step 202: The communications device determines, according to the at least one first parameter value, a quantity of bits for transmission of feedback information associated with the first kind of data.

In this implementation, the target parameter set includes at least one first parameter value used for transmitting a first kind of data and at least one second parameter value that is not used for transmitting the first kind of data. Therefore, the communications device determines, according to the at least one first parameter value, a quantity of bits for transmission of feedback information associated with the first kind of data.

Alternatively, the target parameter set includes at least one second parameter value, where the at least one second parameter value is not used for transmitting the first kind of data. The communications device determines, according to other parameter values except the at least one second parameter value in the target parameter set, the quantity of bits for transmission of the feedback information associated with the first kind of data.

In this implementation, the target parameter set includes at least one of the following parameter sets: a hybrid automatic repeat request (HARQ) feedback timing set or a physical downlink shared channel time domain resource set.

It can be understood that, the communications device determines, according to the parameter values used for transmitting the first kind of data in the HARQ feedback timing set and/or the physical downlink shared channel (PDSCH) time domain resource set, the quantity of bits for transmission of the feedback information associated with the first kind of data.

In this implementation, the communications device may be a terminal or a network device. For descriptions of the terminal and the network device, refer to the corresponding descriptions in FIG. 1. Details are not described herein again.

In an optional implementation of this application, when the communications device is a terminal, the method further includes: receiving, by the communications device, a plurality of kinds of data, where parameters of different kinds of data in the plurality of kinds of data are different, and the plurality of kinds of data includes the first kind of data.

That the parameters of different kinds of data in the plurality of kinds of data are different includes at least one of the following: priorities of different kinds of data in the plurality of kinds of data are different; service kinds of different kinds of data in the plurality of kinds of data are different; reliability requirement parameters of different kinds of data in the plurality of kinds of data are different; feedback delay requirement parameters of different kinds of data in the plurality of kinds of data are different; and transmission time interval lengths used by different kinds of data in the plurality of kinds of data are different.

In an example, the priorities of data may be represented by a quality of service (QoS) parameter. That is, different kinds of data have different QoS parameters. In an example, different kinds of data may have different service kinds. For example, the service kinds of data may include URLLC service data, eMBB service data, and definitely are not limited to the foregoing service kinds. In an example, different kinds of data may be distinguished according to a delay requirement and/or a reliability requirement. For example, the URLLC service data has a relatively short feedback delay, or the transmission time interval length used by the URLLC service data is relatively short. For another example, the eMBB service data has a relatively long feedback delay, or the transmission time interval length used by the eMBB service data is relatively long.

In an optional implementation of this application, the plurality of kinds of data shares the target parameter set. That is, in this implementation, the parameter values in the same target parameter set are used for determining the quantity of bits for transmission of the feedback information associated with the plurality of kinds of data.

In an optional implementation of this application, the method further includes:

determining data kinds of the plurality of kinds of data based on the parameter values in the target parameter set. It can be understood that, the communications device may determine a corresponding data kind according to a parameter value in the target parameter set, where the determined data kind is one kind in the plurality of kinds of data.

In an optional implementation of this application, the method further includes:

determining, by the communications device, whether a parameter value in the target parameter set satisfies a first threshold range, and determining, according to a determining result, whether the corresponding parameter value is used for transmitting the first kind of data.

In this implementation, depending on a different kind of the first kind of data, a corresponding first threshold range is also different. In a first implementation, the first threshold range may be greater than or equal to a first threshold. That is, the first threshold range is from the first threshold to positive infinity. In a second implementation, the first threshold range may be less than or equal to a second threshold. That is, the first threshold range is from the second threshold to negative infinity. In a third implementation, the first threshold range may be greater than or equal to a third threshold and less than or equal to a fourth threshold (herein, the third threshold is less than the fourth threshold). That is, the first threshold range is between the third threshold and the fourth threshold.

Different kinds of data being URLLC service data and eMBB service data respectively is used as an example. The URLLC service data and the eMBB service data correspond to different granularity sizes of the parameter values in the target parameter set. Because the URLLC service data has a higher delay requirement than the eMBB service data, a smaller-granularity parameter value, for example, a smaller-granularity HARQ feedback timing value such as a symbol-level or half-slot-level HARQ feedback timing value, is required, and a large-granularity HARQ feedback timing value (for example, a slot-level HARQ feedback timing value) is not used for transmitting the URLLC service data.

Based on this, in an example, if the first kind of data is the URLLC service data, the communications device determines whether a parameter value in the target parameter set is less than or equal to the second threshold. If the parameter value is less than or equal to the second threshold, the corresponding parameter value is a first parameter value used for transmitting the first kind of data. If the parameter value is greater than the second threshold, the corresponding parameter value is a second parameter value not used for transmitting the first kind of data.

In another example, if the first kind of data is the eMBB service data, the communications device determines whether a parameter value in the target parameter set is greater than or equal to the first threshold. If the parameter value is greater than or equal to the first threshold, the corresponding parameter value is a first parameter value used for transmitting the first kind of data. If the parameter value is less than the first threshold, the corresponding parameter values is a second parameter value not used for transmitting the first kind of data.

In at least one implementation, the method further includes: when the communications device is a terminal, receiving, by the communications device, the first threshold range configured by a network device; or determining, by the communications device, the first threshold range based on a pre-agreed manner.

It can be understood that, when the communications device is a terminal, the first threshold range in this implementation of this application may be configured by a network device. When the communications device is a terminal or a network device, the first threshold range in this implementation of this application may alternatively be determined based on a pre-agreed (for example, protocol agreement) manner.

In an optional implementation of this application, the method further includes: determining, by the communications device according to a granularity associated with a parameter value in the target parameter set, whether the corresponding parameter value is used for transmitting the first kind of data. When the target parameter set includes an HARQ feedback timing set and/or a physical downlink shared channel time domain resource set, the communications device determines, according to a duration granularity associated with a parameter value in the target parameter set, whether the corresponding parameter value is used for transmitting the first kind of data.

In an example, the communications device may determine, according to a duration unit corresponding to a parameter value in the target parameter set, whether the corresponding parameter value is used for transmitting the first kind of data. Different duration units correspond to different duration granularities. For example, the duration unit is a slot, a symbol, half of a slot, or the like.

In this implementation, because different kinds of data correspond to different granularity sizes of the parameter values in the target parameter set, the communications device determines, according to the duration granularities corresponding to the parameter values in the target parameter set, whether the corresponding parameter values are used for transmitting the first kind of data. In an example, if the data is URLLC service data, this kind of data has a relatively high delay requirement. Therefore, a smaller-granularity parameter value, for example, a smaller-granularity HARQ feedback timing value such as a symbol-level or half-slot-level HARQ feedback timing value, is required.

In an optional implementation of this application, the quantity of bits is a quantity of bits of the feedback information transmitted by a physical channel. Alternatively, the quantity of bits is a quantity of bits of the feedback information transmitted by a time unit. For example, the quantity of bits is a quantity of bits of the feedback information transmitted by a slot or a sub-slot.

In an optional implementation of this application, the obtaining, by the communications device, a target parameter set includes: when the communications device is a terminal, obtaining, by the communications device, the target parameter set configured by a network device; or obtaining, by the communications device, the target parameter set based on a pre-agreed manner.

In this implementation, in an implementation, the communications device (namely, the terminal) may obtain the target parameter set configured by the network device through dedicated signaling. In another implementation, the communications device may alternatively obtain the target parameter set based on the pre-agreed manner (for example, a protocol agreement manner).

In an optional implementation of this application, when the communications device is a terminal, the method further includes: sending, by the terminal, the feedback information satisfying the quantity of bits to the network device.

In an optional implementation of this application, when the communications device is a network device, the method further includes: receiving, by the network device from a terminal, the feedback information satisfying the quantity of bits.

The method for determining uplink control information in this implementation of this application is described in detail below by using an example in which the communications device is a terminal and with reference to specific examples.

EXAMPLE 1

A base station configures an HARQ feedback timing set K₁: {1 slot, 2 slots, 3 slots, 4 slots} for the terminal. Because URLLC service data has a relatively high delay requirement, HARQ feedback timing values form 2 slots to 4 slots are not used for transmitting the URLLC service data. Therefore, when determining a quantity of bits of feedback information for the URLLC service data, the terminal determines the quantity of bits of the feedback information only according to 1 slot. Alternatively, the terminal determines, according to the delay requirement of the URLLC service data, a subset {tilde over (K)}₁: {1 slot} satisfying the delay requirement from the HARQ feedback timing set K₁, and determines the quantity of bits of the feedback information for the URLLC service data based on K₁.

For details, reference may be made to FIG. 3. If the quantity of bits of the feedback information is determined by using the at least one first parameter value that is only used for transmitting the first kind of data in this implementation of the application, an information sequence fed back in a slot 4 is only {bs3}. However, in the existing solution, the information sequence fed back in the slot 4 includes {b_(s0), b_(s1), b_(s2), b_(s3)}, while {b_(s0), b_(s1), b_(s2)} is redundant information for the first kind of data.

In other words, when determining the quantity of bits of the feedback information for service data of which a delay of the feedback response information is less than or equal to 1 slot, the terminal determines the quantity of bits of the feedback information only according to 1 slot.

For eMBB service data, because a delay requirement of the eMBB service data is not high, the HARQ feedback timing values form 2 slots to 4 slots are used for transmitting the eMBB service data. Therefore, when determining a quantity of bits of feedback information for the eMBB service data, the terminal may determine the quantity of bits of the feedback information according to 2 slots to 4 slots. Alternatively, the terminal determines, according to the delay requirement of the eMBB service data, a subset {tilde over (K)}₁: {2 slots, 3 slots, 4 slots} satisfying the delay requirement from the HARQ feedback timing set K₁, and determines the quantity of bits of the feedback information for the eMBB service data based on {tilde over (K)}₁.

EXAMPLE 2

A base station configures an HARQ feedback timing set K₁: {2 symbols, 4 symbols, 7 symbols, 10 symbols, 1 slot, 2 slots, 3 slots, 4 slots} for the terminal. Because URLLC service data has a relatively high delay requirement, slot-level HARQ feedback timing values are not used for transmitting the URLLC service data. Therefore, when determining a quantity of bits of feedback information for the URLLC service data, the terminal determines the quantity of bits of the feedback information only according to 2 symbols, 4 symbols, 7 symbols, and 10 symbols. Alternatively, the terminal determines, according to the delay requirement of the URLLC service data, a subset {tilde over (K)}₁: {2 symbols, 4 symbols, 7 symbols, 10 symbols} satisfying the delay requirement from the HARQ feedback timing set K₁, and determines the quantity of bits of the feedback information for the URLLC service data based on {tilde over (K)}₁.

EXAMPLE 3

The terminal determines a PDSCH time domain resource set according to a protocol agreement or configuration by the base station configures. As shown in Table 1, column L represents a PDSCH duration length (that is, a quantity of time domain symbols). Because

URLLC service data has a relatively high delay requirement, a short TTI is required for transmission. For example, a row in which a value of column L is greater than 4 is not used for transmitting the URLLC service data. Therefore, when determining a quantity of bits of feedback information for the URLLC service data, the terminal determines the quantity of bits of the feedback information based on values corresponding to rows other than the 13^(th) row and the 14^(th) row as shown in Table 1.

For eMBB service data, because a delay requirement of the eMBB service data is not high, it is unnecessary to use a short TTI for transmission. For example, a row in which a value of column L is greater than 4 is used for transmitting the eMBB service data. Therefore, when determining a quantity of bits of feedback information for the eMBB service data, the terminal determines the quantity of bits of the feedback information based on values of the 13^(th) row and the 14^(th) row as shown in Table 1.

The communications device obtains a target parameter set, determines, according to at least one first parameter value used for transmitting a first kind of data in the target parameter set, a quantity of bits for transmission of feedback information associated with the first kind of data, and removes at least one second parameter value that is not used for transmitting the first kind of data so that the at least one second parameter value is no longer used as a basis for determining the quantity of bits of the feedback information associated with the first kind of data, thereby avoiding redundant information in the feedback information.

An implementation of this application further provides a communications device. FIG. 4 is a schematic structural composition diagram of a communications device according to an implementation of this application. As shown in FIG. 4, the communications device includes an obtaining unit 31 and a determining unit 32, where

the obtaining unit 31 is configured to obtain a target parameter set, where the target parameter set includes at least one first parameter value and at least one second parameter value, the at least one first parameter value is used for transmitting a first kind of data, and the at least one second parameter value is not used for transmitting the first kind of data; and

That the parameters of different kinds of data in the plurality of kinds of data are different includes at least one of the following: priorities of different kinds of data in the plurality of kinds of data are different; service kinds of different kinds of data in the plurality of kinds of data are different; reliability requirement parameters of different kinds of data in the plurality of kinds of data are different; feedback delay requirement parameters of different kinds of data in the plurality of kinds of data are different; and transmission time interval lengths used by different kinds of data in the plurality of kinds of data are different.
